If you have landed on this page, you must be looking for information about butterfly valves. This article aims to deliver a complete overview of butterfly valves, their types, functions and applications. Scroll down and give it a read!
What is a Butterfly Valve?
High performance Butterfly valves are quarter-turn valves. Since their structure resembles the body structure of a butterfly, they received their names from a butterfly.
This type of valve is used to control and regulate the flow of a medium. These valves come with extremely tight seals that help control the flow of large fluid volumes.
Components of Butterfly Valve
Butterfly valves are made of only four components in their main body. They are as follows:
- valve disk
- valve body
- valve seat
- valve stem
The working mechanism is also pretty simple and efficient as the components are fewer.
Types of Butterfly Valves
Generally, butterfly valves are classified into two types. They are as follows:
- Wafer Type Butterfly Valve
- Lug Type Butterfly Valve
Let’s talk a little about these types of butterfly valves.
Wafer Type Butterfly Valve
This type of valve sits in between pipe flanges. The flange bolts then surround the body of the butterfly valve. Users can install wafer-type butterfly valves easily, and it is easy to maintain.
Lug Type Butterfly Valve
This type of valve comes with protruding lugs around its body. The lug-type butterfly valves allow passage to bolt holes when they fit the flanges.
Furthermore, butterfly valves are divided into different categories based on their construction materials. Some of them are as follows:
- Aluminium Butterfly Valve
- Stainless Steel Butterfly Valve
- PP Butterfly Valve
- Ductile Iron Butterfly Valve
- Cast Steel Butterfly Valve
- Cast Iron Butterfly Valve
- SG Iron Butterfly Valve
These valves are not only different in construction materials, but their mechanisms are also different.
Functions
Butterfly valves can work at extremely low pressure and temperature. Hence, they are also called low temperature valves. The functions of these valves are as follows:
- Regulation of flow of large volumes of fluid.
- These valves isolate the fluid flow as per necessity.
- Butterfly valves can also prevent the back-flowing of fluid inside pipelines.
Though butterfly valves are efficient in functionality, butterfly rubber lined valves improve overall performance.
Application of High Performance Butterfly Valves
You can already decipher that these valves are widely used in liquid industries. Let’s take a proper look at the industries they are applied in. They are also used in regulating gaseous flow.
- Aerospace Sectors
- Compressed Air Applications
- Corrosive Processing
- District Heating, Mining, and Shipyards
- Gas Application
- HVAC
- High-pressure and High-Temperature water and steam services
- Irrigation and Agricultural Needs
- Lubrication
- Petroleum Industries
- Refrigeration and Air Conditioning
- Sanitary Valve Applications
- Slurry Application
- Sprinkler Valve Applications
- Vacuum Service
- Wastewater Treatment
Since their mechanism and maintenance do not take any hassle, they are widely used for various industrial purposes.
Advantages of Butterfly Valve
These low temperature valves are always in high demand in the market. Needless to say, they offer a long list of advantages and are in high demand. Let’s check out the benefits:
- Butterfly valves have a compact structure and do not take up much space.
- A butterfly valve is extremely lightweight, and a piping system can easily accommodate it.
- These valves are quick and easy to operate because of low torque operations.
- As they are made of only 4 components, they are easy to install and maintain throughout the year.
- They are pocket-friendly and durable.
- Since butterfly rubber lined valves are efficient and fast in their work, they consume less energy.
